This is an excellent example of a late production Harrington & Richardson, Reising Model 50 submachine gun. It is a blow-back operated SMG that was used for a short time by the USMC in WWII as a war expedient substitute for the Thompson submachine gun. The big advantage was they were faster and much cheaper to produced as well as shorter and lighter. The receiver is marked " MODEL 50- H.&R. REISING CAL. 45"/HARRINGTON AND RICHARDSON ARMS CO./WORCHESTER, MASS. U.S.A. PAT. PENDING", with serial number "S4997" towards the rear of the receiver. The right side of the receiver has the three position (SAFE/SA/FA) selector switch and it is fitted with a stamped sheet metal adjustable rear sight with blade front sight. The barrel has the cooling fins in the middle and the muzzle is fitted with a compensator/muzzle break. It has the all parkerized metal finish and it fitted with a one-piece walnut stock with sling swivels mounted on the underside of the stock. The cocking lever is found on the underside of the forend. The magazine well I s "crimped" on the sides to prevent use of higher capacity magazines (1 compatible magazine included) Approximately 100,000 produced through WWII.

Excellent with 98% of the arsenal parkerized finish overall with only minor edge and high spot wear with the bolt assembly still in the white as originally manufactured. The walnut stock is excellent with no visible handling marks with a nice oil finish.
